20 to 25 pounds is the average weight of a complete watermelon, such as those found at grocery stores. A watermelon weighing 20 pounds contains around 14 pounds of fruit. There are about 1,200 types of watermelon ranging in weight from 1 to 200 pounds.
The flesh of the majority of watermelon types is red, pink, orange, yellow, or white. The Charleston Gray watermelon is a popular among commercial watermelon growers due to its greater disease resistance, high yields, and ease of field-to-market shipping. The size and quality of watermelons are affected by a number of elements, including water, pollination, soil, and weather conditions.
